Rs-232 Interface Commands - Multitech CommPlete MT5634HD8 User Manual

N n Modulation Handshake{xe "Modulation Handshake"}{xe "AT
commands:N"}{xe "handshake modulation"}
n = 0 or 1
Default: N1
This command controls whether or not the local modem performs a negotiated
handshake with the remote modem at connection time, when the communication
speed of the two modems is different.
N0 enables handshaking only at the communication standard specified by S37 and
the ATB command.
N1 always begins the handshake only at the communication standard specified by
S37 and the ATB command, but allows fallback to a lower speed as the handshake
proceeds. This is the default.
\T n
Inactivity Timer{xe "AT commands:\T"}{xe "Inactivity Timer
command"}
n = 0
Default: \T0
The inactivity timer specifies the length of time, in minutes, that the modem will
wait before disconnecting when no data is sent or received. This timer is specified in
register S3. The \T0 command disables the inactivity timer.
Y n Long Space Disconnect{xe "AT commands:Y"}{xe "long space
break"}{xe "Long Space Disconnect command"}
n = 0
Default: Y0
When two modems are connected in reliable mode, a link disconnect request packet
is sent to request a disconnect. In non-error correction mode, there is no "polite" way
to request a disconnect. As a result, some "garbage" may be received when a hang-up
command is issued.
Y0 disables the modem's use of the break signal{xe "break signal"}.

RS-232 Interface Commands

These commands define how an MT5634HD8 modem will use and respond to
standard RS-232{xe "RS-232C"} signals.
&C n
Carrier Detect Control{xe "RS-232C:controls"}{xe "Carrier Detect
Control command"}{xe "CD signal:control of"}{xe "AT commands:&C"}
n = 0 or 1
Default: &C1
The &C command lets you control the Carrier Detect (CD) signal on the RS-
232/V.24{xe "RS-232C"} interface. This is a signal from the modem to your computer
indicating that the carrier signal is being received from a remote modem.
Normally, CD goes "high" (turns on) when the modem detects a carrier on the
communications link, and "drops" (turns off) when it loses the carrier. By using &C,
you can force the signal to stay high, or to drop momentarily when the remote
modem disconnects. This option is useful with some CBX phone systems{xe "CBX
phone systems"} and mainframe front ends, which require CD to act in this manner.)
